Abstract
A relay having a contact spring connected to an armature in which the contact spring is constricted near the free edge of the armature and is broadened into a T-shaped end to provide a double contact or bridge contact relay further includes supporting tabs applied to each of the transverse legs of the contact spring. The supporting tabs are struck by the armature during armature motion directed toward opening of the contacts. This transmits a jolt of force in the immediate proximity of the contact pieces during opening of the contact pieces in order to break any welding or adhesion of the contacts. The relatively weak spring modulus for ensuring closing of the contacts is retained.
